When I set up a scene in Poser, it often happens to me, that the scene will exceed the limits of my video card (GTX 570 / 1,2GB).
In this case, after starting the Octane plug in, a system window popped up, telling me that the card wasn't able to allocate enough memory, to handle all of that (sorry, I don't know the exact words, but it was something to this extent). The plug in then closed itself and I found myself back in Poser, where I could adjust the scene again.
If this happens now, with ver. 1.02p, I still get the same message, but at the same time Poser crashes completely now. There's no chance any more to do anything with Poser, beside re-starting it.
Does this happen to others, too?
With the next release I've loosen off the cuda error trapping, so now if you get a cuda error, the plugin will remain open. If it's error 999 (your card didn't start rendering), you can then Reset the card through the Cuda Devices tab. If you run out of memory, you can still continue the render (at your own risk!), or can at least tweak the nodes in the Materials tab to save some memory. I think this should help a lot.
